- Configure the model for two surrogate species:
- Non-depositing noble gas (NGAS)
- Depositing small particle (RNUC)
- Assign both to the same computational particle
- Run the calculation for a continuous unit emission with NO decay
- Concentration, deposition, and decay are from the post-processing step

Run Model
Apply emissions and dose conversion factors
- In post processing each radionuclide in activity file is assigned a surrogate species
- Activity file can be modified for each phase of the accident
- No limit to the number of radionuclides assigned
Cloud-shine and Ground-shine
- Total air and ground dose computed (1 REM = 10 mSV)
- 3D particle near source results are sensitive to grid size
- Note the dependence of deposition to the resolution of the precipitation field
